Not able to detect trackpad events on macOS using IOKit hidmanager - IOHIDManagerRegisterInputValueCallback

Question

I am trying to detect mouse events along with device details on macos. The code detects external mouse events but doesn't detect internal trackpad events. Surprisingly the same code works on

• Intel macbook pro with Ventura
• M1 macbook pro with Ventura
• M1 macbook pro with Sonoma 14.3

It doesn't work on

• M3 macbook pro with Sonoma 14.6
• M2 Macbook air with Sonoma 14.4

Code

#include <iostream>
#include <IOKit/hid/IOHIDManager.h>
#include <CoreFoundation/CoreFoundation.h>

void mouseEventCallback(void *context, IOReturn result, void *sender, IOHIDValueRef value) {
    std::cout << "Mouse event" << std::endl; // Prints only external mouse events. Doesn't work for internal trackpad.
}

int main() {
    IOHIDManagerRef manager = IOHIDManagerCreate(kCFAllocatorDefault, kIOHIDOptionsTypeNone);
    
    // Create a matching dictionary for mouse and trackpad devices
    CFMutableDictionaryRef matchingDict = CFDictionaryCreateMutable(kCFAllocatorDefault, 0,
        &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks);
    
    // Add matching criteria for mouse and trackpad devices
    CFDictionaryAddValue(matchingDict, CFSTR(kIOHIDDeviceUsagePageKey), CFNumberCreate(kCFAllocatorDefault, kCFNumberIntType, (const int[]){1})); // Generic Desktop Controls
    CFDictionaryAddValue(matchingDict, CFSTR(kIOHIDDeviceUsageKey), CFNumberCreate(kCFAllocatorDefault, kCFNumberIntType, (const int[]){2, 5})); // Mouse, Touchpad

    // Set the matching criteria
    IOHIDManagerSetDeviceMatching(manager, matchingDict);
    
    // Register the callback for input value changes
    IOHIDManagerRegisterInputValueCallback(manager, mouseEventCallback, NULL);
    
    // Open the HID manager
    IOHIDManagerOpen(manager, kIOHIDOptionsTypeNone);
    
    // Schedule the HID manager with the current run loop
    IOHIDManagerScheduleWithRunLoop(manager, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode);
    
    // Run the loop to listen for events
    CFRunLoopRun();
    
    // Clean up
    CFRelease(matchingDict);
    CFRelease(manager);
    
    return 0;
}

Compile command clang++ -o mouse mouse.cpp -framework IOKit -framework CoreFoundation

I have also tried external libs like https://github.com/icculus/manymouse but the same issue persists. Also, when I use IOHIDManagerRegisterDeviceMatchingCallback both external mouse and trackpad gets registerd but the events are not detected from the internal trackpad.

I tried using CGEventTapCreate which detects events from both trackpad and external mouse on all devices but, I can't use it as it doesn't give device details along with events (Product id, vendor id etc).

// This works
#include <iostream>
#include <ApplicationServices/ApplicationServices.h>

// Event tap callback function
CGEventRef eventTapCallback(CGEventTapProxy proxy, CGEventType type, CGEventRef event, void* userInfo) {

    if (type == kCGEventLeftMouseDown || type == kCGEventRightMouseDown || type == kCGEventOtherMouseDown) {
        CGPoint mouseLocation = CGEventGetLocation(event);
        std::cout << "Mouse Clicked at: (" << mouseLocation.x << ", " << mouseLocation.y << ")" << std::endl;
    }
    else if (type == kCGEventScrollWheel) {
        // For scroll events
        CGPoint scrollDelta = CGEventGetUnflippedLocation(event);
        std::cout << "Mouse Scrolled at: (" << scrollDelta.x << ", " << scrollDelta.y << ")" << std::endl;
    }

    return event;
}

int main() {
    // Create an event tap to monitor mouse events
    CGEventMask eventMask = CGEventMaskBit(kCGEventLeftMouseDown) |
                            CGEventMaskBit(kCGEventRightMouseDown) |
                            CGEventMaskBit(kCGEventOtherMouseDown) |
                            CGEventMaskBit(kCGEventScrollWheel);

    CFMachPortRef eventTap = CGEventTapCreate(kCGSessionEventTap, kCGHeadInsertEventTap, kCGEventTapOptionListenOnly, eventMask, eventTapCallback, nullptr);
    if (!eventTap) {
        std::cerr << "Failed to create event tap." << std::endl;
        return 1;
    }

    // Create a run loop source and add it to the current run loop
    CFRunLoopSourceRef runLoopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, eventTap, 0);
    CFRunLoopAddSource(CFRunLoopGetCurrent(), runLoopSource, kCFRunLoopCommonModes);
    CFRelease(runLoopSource);

    // Enable the event tap
    CGEventTapEnable(eventTap, true);

    // Run the run loop to process events
    CFRunLoopRun();

    return 0;
